چکیده
Halogen exchange reactions between hexacoordinate tin dihalides (LnCH2)2SnX2 and (LnCH2)2SnY2 (LnCH2 = C,O-chelate n-membered lactamomethyl ligand, n 5–7, X, Y Cl, Br, I) produce mixed (LnCH2)2SnXY. Along with the signals of original complexes, NMR 119Sn spectra solutions containing two different homodihalides show third signal a median chemical shift. The results monitoring studies, conductivity data quantum-chemical calculations suggest that readily form in solutions, although these complexes have not been isolated as individual compounds.

Ab Initio Studies on the Interplay between Unconventional B•••X Halogen Bond and Lithium/Hydrogen/Halogen Bond in HB(CO)2•••XCN•••YF (X = Cl, Br; Y = Li, H, Cl) Complexes
In this paper, ab initio calculations were performed on the ternary complex formed by HB(CO)2, XCN (X = Cl, Br) and YF (Y = Li, H, Cl). In these complexes boron act as a non-classical electron donor to form a unconventional halogen bond. The cooperative effect between the B•••X halogen bond and lithium/hydrogen/halogen bond was investigated. The calculated results show that the B•••X and N•••Y ...
متن کاملHalogen as halogen-bonding donor and hydrogen-bonding acceptor simultaneously in ring-shaped H3N·X(Y)·HF (X = Cl, Br and Y = F, Cl, Br) complexes.
A series of ring-shaped molecular complexes formed by H(3)N, HF and XY (X = Cl, Br and Y = F, Cl, Br) have been investigated at the MP2/aug-cc-pVTZ level of theory. Their optimized geometry, stretching mode, and interaction energy have been obtained. We found that each complex possesses two red-shifted hydrogen bonds and one red-shifted halogen bond, and the two hydrogen bonds exhibit strong co...

MP2 calculations with cc-pVTZ basis set were used to analyze intermolecular interactions in F3CX···YLi···NCCN and F3CX···NCCN···LiY triads (X = Cl, Br; Y = CN, NC) which are connected via halogen and lithium bonds. Those complexes with the role of LiY as halogen acceptor and lithium donor show cooperativity with energy values ranging between -1.97 and -2.92 kJ mol...
